Taxonomy involves using controlled vocabularies to organize and classify content. Controlled vocabularies are pre-selected sets of terms that help describe and tag content. This tagging creates descriptive metadata, which is essentially data about data.

Each time you add a new article or page to your website, you will need to use these pre-defined, controlled terms to label your content. This process occurs behind the scenes. While not directly visible to users, it helps the website's backend system understand and manage the content effectively. For example, on an information website about animals, terms like "Mammals," "Birds," and "Reptiles" are part of the controlled vocabulary. Each article is tagged with these terms to create metadata. This metadata makes it easier for the backend to sort and direct users to the right content, ensuring a smooth and organized user experience.^[1]
